Unable to merge multiple solids to one solid for FEM

Postby Prakash » Sat May 15, 2021 5:55 pm

Hi
i'm trying to merge multiple parts into single solid for FEM.
Tried with "Part-> Embed, Connect and Union" it creates single object in Tree view but when i select "Part->Check Geometry->Run Check" i see that there are still 2 solids.
Checked object: Unnamed1.Embed (Embed):
Shape type: Compound
Vertices: 604
Edges: 910
Wires: 320
Faces: 308
Shells: 2
Solids: 2
CompSolids: 0
Compounds: 1
Shapes: 2147
----------
Area: 1362685.85
Volume: 1268287.15
Length: 418901.89
Orientation: Forward

How can merge 2 solids to one.
Have attached freecad file for your reference
Freecad Version: 0.19
Revision Number: 24291 (Git)

Thanks for your time.

with warm regards
Prakash

Switch to wireframe mode and zoom in on the connection. On the inner corner there is a 46 micrometer gap.

Thank you
Fixing the Gap worked.
Now "Part->Connect" is creating single solid.

but having issue with Stress plot from FEM Result (Not sure if this is linked to current issue)
